    摘要: A high efficiency condenser, in one embodiment, includes a phase change material in thermal contact with the condenser to assist in cooling the condenser during operation and particularly during pull-down operation to improve the cooling capacity of a compressor. In a preferred embodiment of such a system, a coaxial tube carrying the refrigerant through the condenser includes an inner conduit for the refrigerant and a coaxially arranged outer jacket with phase change material for extracting heat from the compressed refrigerant. In another embodiment, a secondary condenser is provided in a secondary coolant circuit and is in thermal contact with the primary condenser. Variable speed fans are associated with the condenser(s) and can be operated in the high speed (turbo) mode during pull-down of a refrigeration system for providing sufficient cooling capacity during a pull-down mode of operation.

    摘要: A tube and fin-type evaporator is provided for a refrigerator having trapezoidally shaped fins with the wider portion of the fins disposed upstream in the cooling air flow path through the evaporator. The refrigerant tube passes through at least two rows of openings in these fins, and those openings are staggered and of different length to enhance turbulence and reduce tube shielding within the cooling air flow. Projections (dimples) on the fins adjacent the downstream side of each opening are provided to reduce dead air space downstream from the tube. Further, the openings are provided with collars to increase heat transfer between the fins and the tube. These projections and collars also serve to increase rigidity of the fins. The present invention enables the use of relatively small diameter, thin walled refrigerant tubes within the evaporator. Also, the tubes can be hydraulically expanded within the fins to enhance fin to tube contact and decrease heat transfer resistance.
